I noticed that when the phone is rotated, the onCreate method is called again, and this causes me big problems .. From application logic to display issues.

So, what i would like is to find a way to force the screen to portrait mode, and no matter how the user rotates the phone, the app to remain still reported to the phone.

Thanks in advance

Add the following to AndroidManfiest.xml for the Activities you want to run only in portrait mode and ignore screen orientation changes.

android:screenOrientation="portrait"
android:configChanges="orientation|keyboardHidden"
